Laser-ablated molybdenum and tungsten atoms were reacted with dioxygen
and O-18-substituted dioxygen. The products of these reactions were i
solated in solid argon matrices at 10 K and studied by matrix infrared
spectroscopy. Analysis of spectra enabled identification of reaction
products, which included MoO2, (O-2)MoO2, MoO3, WO, WO2, (O-2)WO2, and
WO3. Resolution of isotopic splitting due to natural isotopic abundan
ce of the metal verified the presence of a single metal atom in these
molecules and allowed for calculation of bond angles for the molybdenu
m and tungsten dioxide molecules and their dioxygen complexes.
